The author's incision method for endonasal septoplasty is a compromise between the Killian incision that can easily exfoliate mucoperichondrial flap and the modified Killian incision for which the manipulation of septum and suturing of mucoperichondrial flap following collection of septum is easy. First, as illustrated in Figure 1, an incision is made between a and a′ on the median line of the existing modified Killian incision with an interval of approximately 5 mm using a no. 15 scalpel. The incision is extended to both ends of a and a′ in the radial direction that can be reached with clear surgical view. Then, a mucoperichondrial flap is exfoliated by using a D knife, Cottle elevator, and Freer periosteal elevator. Simple suture with 5-0 Vicryl (Ethicon, Inc., Somerville, N.J.) was made at two locations (i.e., at a and a′) after having collected the septum by leaving the L strut (Fig. 1).Time taken for surgery using the author's method was compared with three existing methods to determine
